He specifically said that the video was about a transmitter on a hoseWell if the guy had his transmitter comme loose without a hose (for example the transmitter not being screwed on correctly and actually coming loose) it would not be a loss from a hp-hose but from the entire HP-port. I don't know the exact number on the time it will take to empty the tank, but it will be alot faster than with an hp-hose.
